Lakewood Model 2255 Multi-Boiler Controller
Discontinued Model
 The Lakewood Model 2255 Multi-Boiler Controller uses LonWorks® Technology for accurate control of your boiler system. The system will allow control of 1-to-8 boilers using the cycle/sample or continuous sample method. Two water meter inputs are available which can be used to feed chemicals. Each conductivity input contains its own microcontroller which talks directly to the relay that controls the motorized ball valve for each boiler. The 2255 can be programmed with LRWS (Lakewood Remote Windows Software) or from the keypad of the controller. LRWS allows data to be accumulated on all boilers, water meter inputs, chemical pump on time and more. LRWS will also allow the user to make graphs of the downloaded information, print conductivity values or export information for use with datalogging spreadsheets.

Features
Steam flashing detector and compensation. Control and monitor 1 to 8 boilers. Future boilers can be added to an existing system. Boiler input(s) can be substituted to monitor condensate. Sample/cycle or continuous conductivity control of blowdown. Use sample/cycle for blowdown less than 1,000 lb./hr. Use continuous for blowdown greater than 1,000 lb./hr. Two water/flowmeter inputs provided. Can feed chemical according to water meter, percent of bleed, or percent on-time. Interactive communications software datalog and control (-RS2L & -RTC Options). Four different languages.
English Spanish (standard)
English French (optional)
English German (optional)
Benefits
Accurate control of boiler conductivity. Control results in fuel savings by preventing excessive blowdown. Prevents carryover due to excessive conductivity. One controller can monitor and datalog up to 8 Boilers.
